` CINCINNATI, OHIO, .A CORPORATION OF OHIO SELF-CLOSING FAUCET.

Specification of Letters Patent. Patented June 6; 1922.

- Application filed April 19, 1919. serial No. 291,316.

To all whom t may concern.'

Beit known that I, JOHN MGNEIL, a' citlzen of the United States ofAmerica, yand a resident of Cincinnati, in the county of Hamilton andState of Ohio, have invented a new and useful Improvement inSelf-Closing Faucets, of which the -following is a specification;

An object of my invention 1s to produce an improved faucet which isparticularlyl adapted to be used in lavatories, whlch 1s of theself-closing type, and which will prevent water-hammer occurring in theclosing operation.

A further object is to produce a lavatory faucet which is of theself-closing type and in which uniformity of closing action is hadregardless of the amount of suspended sediment or the corrosive actionof the water passing therethrough.

These and other objectsare attained in the faucet described in thefollowing specification and illustrated in the accompanying drawings, inwhich- F ig. 1, is a sectional view of a faucet embodying my invention,showing the elements thereof in closed position.

Fig. 2, is a sectional elevation of a faucet embodying my invention,showing the elements thereof in open. position.

Fig. 3, is a sectional fragmental view of a detail of the faucetembodying my invention.

My improved faucet has a casing'l, at the lower end of which a nipple 2is provided for admitting water thereto, a discharge nozzle 3 beinglocated at the upper end of the casing. A handle 4 is provided, which isheld in position by housing 5, located above the casing. A member 6,which is screwed within the upper end ofthe easing, contains the valveyseat 7 which is preferably of some suitable compressive material, thismember being also used to secure housing 5 at its upper end. A cap 8 isreciprocally mounted Within the housing 5, and is held against the lowerend of handle 4 by means of a 'spring 9 which bears at its lower endagainst member 6. This holds the handle in the position shown in Fig. 1,and permits it to be returned to this position after having been movedto faucet opening position, as shown in Fig. 2. A valve stem 10, whichcarries valve 11 at its lower end, is held against the inner surface ofcap 8 by means of a spring 12, which bears at itsupper end against anadjustment nut 13, mounted upon the valve stem and at its lower endagalnst the packing 14 which is located within member 6. Beneath thepacking 14 a passage 15, which communicates with the lower chamber ofthe casing, is provided, this passage being provided with ports 16,which communicate wlth a chamber 17 froml which the discharge nozzle 3extends. At the lower end of valve 11 a packed plunger 18 is provided,which is -reciprocally mounted within acup 19, in the 1nlet passage andat the upper end of nipple 2. A pointed pin 2O is located within apassage 21, within the plunger, the passage terminating at its bottom ina port 22 and at its upper end in a chamber 23, which is provided withaport 24 communicating with the lower chamber 25 lof the casing. Ports 26are located beneath cup or cylinder 19 and connect the interior ofnipple 2 with chamber 25 of the casing.

In opening my improved faucet for a discharge of waterfthrough nozzle 3,handle 4 is tilted to the position shown in Fig. 2.

This presses upon cap 8, and therefore upon stem 10 of the valve,compressing springs 9 and 12, thus forcing valve 11 to move away fromseat 7 and open the direct passage from the water supply through ports26, chamber` 25, passage 15, port 16, chamber 17 and nozzle 3.Simultaneously with the action of the valve the movement of plunger 18downwardly within cylinder 19, will cause pin 20 to rise and permit thepassage of water through passage 21 and. port 24 and thence to bedischarged through the faucet. When this water has been discharged pin2O will drop back to its normal position closing port 22 and when handle4 is released water will pass through the chamber 25 aroundthe packingin plunger 18 and gradually back into the lower portion of cup 19 andpermit the springs 9 and 12 torestore the parts of the faucet to normalcondition, thus bringing the valve back into engagement with valve seat7. The faucet thus gradually closes itself and prevents water-hammer byhaving the water gradually closed off.

An advantage of my invention over other previous inventions known to meis that the pin 2O moves at each operation of the water, thus clearingthe passage 21 of any sediment or corrosion, and also maintaining aclear port 22. There can therefore be no hesitancy lll@ or refusal ofthe faucet to act properly even after long periods of use thereof.

Having thus described my invention what I claim is 1. A faucetcomprising a casing having inlet and discharge passa es, a cup having animperforate bottom an being in the inlet passage. and in axial.alignment with the casing, avalve in the casin ,-a valve plunger at thelower end of the va ve and enga g the inner walls of the cup,`saidplunger aving an internal passage and a port at the lower end of thepassage forming communication between the passage andthe inside of thecup, and a port at the upper end of the passage forming communicationwith i the l inlet passage, a pin located within the pasagainst the wallsurrounding the port in thev sage in the plunger, and adapted to seatbottom thereof.

2. A faucet comprising a casing having inlet and discharge passages, acup having an imperforate bottom and being in the inlet passage and inaxial alignment with the casing, a housing having an open top and are-entrant annular flange mounted above the casing, a reciprocating capwithin the housing, a valve in the casing, a valve stem extending intothe housing, and adapted.-

to engage one side of the cap, a valve plum upon its seat.

ger at the lower end of the valve and engaging the inner wall of thecup, said plunger having an internal passage and a port` at the lowerend of the passage forming communication between the passage and the`inside of the cup, and a port at the upper end' of the passage formingcommunication ywith the inlet passage, a pin' located within the passagein the plunger adapted to seat against the wall surrounding the port Vinthe bottom thereof, a handle having at lts lower end a substantiallylflat and circular disc adapted to engage on its lnner surface with l Intestimon whereof, I have hereunto subscribed my name this 16th day ofApril,

JOHN MONEIL.
